Why This Universe

Next time on why this universe, we're going to pick up where we left off here today and talk more about string theory. We'll describe some of the different kinds of string theory that we explored over the years and talk about how they're related to each other through what we call duality. And oh, yeah, we'll talk more about those 26 dimensions of space and time, how they might be hiding from us, and how we might be able to find them one day in an experiment.
